Advice on cracked oil filter assembly

[Crewser1989]

Hey there VAF folks!

Just looking for some advice on how to tackle this oil filter assembly issue. It’s off a Lycoming O320 H2AD and has two cracks by the threads from what I can only assume was over tightening.

At any rate, I’ve only found one for sale and it’s being sold ‘as-is’ so I’m retaining some skepticism that it’s a good part.

Anyone else run into this issue or have advice on how to proceed?

Thanks in advance!

Sorry to say but it’s trashed and you’ll need a new one. As you surmised, someone over torqued the fittings and cracked both threaded holes. What a shame.

The equivalent P/N is LW16118, and those are also available new from different sources.

Yep, needs replacement.

Take it to a Tig welder, if you can't find a reasonable replacement. Most of the Lyc Alum parts are 6xxx series and easilly welded. Will need a machine shop to re-tap the threads and mill the surface flat and chamfer after welding. I assume Divco would do this for a flat fee of $50-100 and may be easier to just ship off. It is a pretty easy job to fix that.

Someone really screwed that up.

Since you don't want to lose your oil in flight, I would take the recommendation to send that to DIVCO and let them fix it if they will. This is not somewhere you want someone to go to school at your expense.

$3,409 (and 45 cents) for that part! Must be made from unobtainium. Wow!

Try Aircraft Specialites in Tulsa

They are essentially next door to Divco, and sell every part you need to build a Lycoming. If Divco can’t fix it, then it can’t be fixed, and ASSI will work with you on options.

Or…Aircraft salvage yards might have one.

Would not fit - My T-18 (H2AD) let me know if interested.

Thanks for the help everyone! I ended up being able to snag one off eBay. Swapped it out and seemed like a good fit. Hopefully this one stays together for many more flying hours!

That’s interesting. I wonder what the variation between the H2ADs is?

It fit the H2AD, but not enough room between it and the T-18 engine/gear mount.
I should have stated that better.
